- How to keep older Macs secure: a geeky approach (run Catalina on unsupported Macs) Posted on October 8th, 2019 by Jay Vrijenhoek.

But I would rather buy a second generation silicon mac to truly take advantage of the new OS features and remain on Catalina (or HS) for everything else.

The tool extends the list of compatible hardware to the Mac Pro, iMac and MacBook Pro computers released in early 2008, Aluminum Unibody MacBooks or MacBooks Air manufactured in late 2008, or white MacBooks and Mac Minis produced in early 2009.
Get the macOS Catalina Installer app and make sure you have access to a compatible USB drive
To be able to use the app you must make sure that you have a USB drive that has at least 8 GB available, and that you have the macOS 10.15 Catalina installer app on your Mac.
Macos Catalina On Unsupported Macs
Note that you can download the macOS image from the Mac App Store application only on a machine that supports Catalina: otherwise, you must find an alternative solution.
For your convenience, macOS Catalina Patcher offers you the possibility to download the image through its interface: just navigate to the Tools menu.
At the same time, you must prepare the USB drive with the help of the built-in Disk Utility application: just format the disk using the Mac OS Extended (Journaled) standard.

You have the option to monitor the process in the macOS Catalina Patcher main window, and the utility lets you know when the task is complete.

All things considered, macOS Catalina Patcher is a small and user-friendly utility designed to help you bypass this limitation if your Mac is not in macOS Catalina's compatibility list, created to be used as an unsupported Mac Mojave patch.
